Get Blade Enclosure name and bay position in SCCM via WMI

We're in the process of building a report in SCCM that can give us an overview of how many free slots we have in our blade centers.

We've found that the path root\hpq class HP_BladeEnclosureCS attribute Name SHOULD contain the DNS name of the blade enclosure. Instead it contains the dns name of the current active OA in the bladecenter.

Does anyone know if there's a WMI query that can get the actual blade enclosure name?
